Application filed-September 3,1910. S'erialfl'o.5893.00.

To all-whom itmay concern --'Be that IJEEUGENE L. Knrnsya citizenoftheUnited States; residing 'at Boston, in' the county of Suffolk andState of Massachusetts, have invented certain Improvements in-Holdd'ownsj 'for- Lasting-Machines, of" which the followingdescription, inconnectiomwith' the accompanying drawings,=isaspecification, like reference characters on the drawings indicatinglike parts in the several figures.

This invention relates to hold down devices for use in connection with'bed lasting machines of awell known commercial type, such -for-'example as shown in UfS. Letters patent to -Brock, No. 1,018,477, datedFeb. 27,1912, to-whibh reference may be hadfor the description'ofthe'machine in general.

In important feature 'of' this invention is found in'the'foot. In itspreferred form as shown the foot is of spring metal andisrotatablymounted'on its carrier which in turn ismovable to present thefoot in any desired position lengthwise, laterally or angularly over theshoe. The foot -is formed and mounted toengage 'by'its toe or front endfirst and in practice this is placed-upon the tip of the whilethe=treadle is further depressed. The foot is bent or inclineddownwardly toward the toe and as the downward pressureris applied theengaging portion is-more or less forced forwardly to push against theinnersole lip where it holds the innersole firmly against'the backwardpressure of the lasting plates or wipers. As the downward pressure iscompleted the heel of the hold down descends unyieldingly upon the shoebottom and furnishes the firm abutment to withstand the upward wipe ofthe lasting plates'tendin'g to lift the last. -It will thus be seen thatthis hold down comprises means to press downwardly and slightlyforwardly at the toe, said means being adapted to engage against theinner-sole lip and furnish an abutment therefor'a'nd crowd the innersoleforwardly enough to keep it. straight and smooth, and means also topress hard down upon the ball of the last. The illustrated formationhas'the advantage of holding down upon the toe of the last to an adequate extent and in a satisfactory manner,

toe ofthe innersole just inside of and against the channel lip where itis held and'of holding: down the last'as a' whole by pressure appliedoverthe'ball' and'ata distance from'thewoe-lasting-apparatus whichavoids any'interfermcwwith the use of the wipers or of the hand pincerssometimes employedas auxiliary lasting devices. The downward inclinationof the foot has: the

double advantage "that is gives adequate pressure at the' toe end,'particularly when supplemented bYfllOflCtlOIlfOf the heel of the foot 1upon the "ball of "the 1 last without any upstanding braces"whi'ch would'be a in thewvay of 'thetoe lastingoperationand that the bendorinclination-oftheyielding foot or resilienthold down member enables itto adapt itse'lf i automatically to any spring or'long'itudinal'inclination of the bottoms of the lasts which a're-be'ingused.

A --fu'rther object of the invention is to provide adjustment of thehold down laterally of the shoewhieh may be readily effected arid-whichwill not be likely to be acci denta lly' disturbed during the operationof themaehine.

Further t-featu'res -of novelty relate to mechanism 'for holdiug thehold down desubsequently described.

In 'the drawings Figure -1- is a sectional viewof a'lasting machine withmy improved device incorporated therein. .Fig. 2 is a detailperspectiveshowing the hold down head mounted-inoperative position upon a shoe andthe toe' lasting wipers in inoperative position. Fig.3 is a sectionaldetail showing the means'for frictionally'holding-the carrier-of'thehold down in its adjusted position laterally of the shoe.

in the drawings the reference numeral 2 indicates the frame of themachine. Tothe frame of the machine back of the lasting heads is securedat 4 a sleeve 6 which is held in position upon-a rod 7 by collar" 9.Passing through the sleeve 6 is a hold down post 8 having a slot 10 cuttherein which is engaged'by a:pin 12 seated in the sleeve 6 to preventrotation of the post 8 and permit set screw 18.

lar 22 rigidly secured to the post 8 and carrying a stop pin 24 withwhich a stop pin 26 seated in the block 20' engages when the hold downcarrier 38 is swung into its inoperative position as shown in Fig. 1.The

hold down carrier is automatically swung into this inoperative position,when released from the work, by a spring 30 which is attached at one endto a lug 28 carried by the block-20 and at the other to the collar 16which isrigidly clamped to'the post 8 by the Upon the upper end of theblock 20 is an enlargement having therein ways 36 through which slides ahold down carrier 38. The construction of the ways 36 is such that thecarrier 38 has a free sliding movement therein, and to providesufiicient friction to hold the carrierinadjusted position againstordinary stresses the device shown in Fig. 3 is provided. A hole ismadethrough the enlarged portion of the block 20 extending through tothe carrier 38 and in this hole is seated a cylindrical block 35engaging a slot 41 in the side of the carrier-38 and spring pressedthereagainst by a spring 37 which is backed up by a screwplug 39. Thepressure of the block 35 upon the carrier creates sufiicient friction tohold the carrier in its adjusted'position.

T heaforward end of the carrier 38 is re duced at 40 and through thereduced ortion extends a connector in the form of a olt 42 having a head44 provided with teeth for engaging the innersole and with a thumb nut46. The bolt head thus forms the heel of the hold down foot. Between thehead 44 and the end 40 of the hold down carrier 38 is introduced aresilient hold down foot member 48 which is provided with a slot forthat purpose. A thumb nut 46 enables the hold down foot member 48 to beclamped 'to the hold down carrier in any position of angular adjustment.The forward end of the hold down member .48 is. bent downwardly andprovided with a roughened toe 50 for engagement with the edge of theinnersole. It will be seen that as the toe 50 engages the toe portion ofthe innersole behind the lip and is straightened by further downwardmovement of the hold down arm, the end thereof presses a inst the lipand tends to force the innerso e forwardly to its normal position flushwith the edge of the last.

From the mechanism described, it will be seen that the hold down carrier38 may be swung from its inoperative position, as shown in Fig. 1, 'toits operative position, as shown in Fig. 2, that the carrier may beadjusted laterall or angularly relatively to the shoe and t at the holddownmember 48may be adjusted relatively to the carrier 38.

It remains to provide mechanism for composed ofa part 72 pivoted to thepost 8,

a part 68 pivoted to the pedal lever 60 and an intermediate portion 66having right and left hand threads upon its opposite ends threaded intothe holes into the parts 72 and 68. The length of the connecting rod maythus be'adjusted by turning the part 66 relatively to the parts 72 and68 and the parts may be locked in adjusted position b a set nut 69.

For 100 ing thepedal in depressed position ara-tchet bar 78 having uwardly' directed teeth is provided whic slides in ways in a block 79attached to the frame of the-machine. The ratchet bar is provided with ashoulder 81 engaging the pedallever for sliding engagement and a in 80is passed through the ratchet bar elow the lever. Upon the upperpbrtion, of the block 7 9 are provided lugs carrying a pivot 86 of apawl 84 having downwardly directed teeth which is normally held inengagement with the ratchet bar by a spring 88. A connecting rod 90pivoted to a projection on the pawl 84 extends to and is adjustablyconnected with a knee lever 96 having a knee engaging portion 100 andpivoted at 98 to the machine frame. A lug 94 is pivoted to the kneelever 96 and on the rod which passes through the lug 9.4 are providedset nuts 92' in order that the length of the rod may be adjusted. lVhenthe pedal lever is depressed, it will be seen that the ratchet bar 78 iscarried with it and slides beneath the pawl 84 which prevents returnmovement. When, however, it is desired to re lease thedown hold, theknee lever 100 is pressed which, rocking upon its pivot 98, pulls uponthe rod 90 and unseats the pawl 84 from the ratchet bar 82 thusreleasing the pedal lever which is retracted to normal position by thespring 76.

In the operation of the device, the operator after having placed a shoein position to be lasted upon the machine swings the hold down carrier38 over the innersole of the' shoe and having adjusted laterally,longitudinally and 'angularly of the shoe to the desired position,depresses the pedal lever 60 to move the hold down toward the bottomface of the shoe. The lowermost or'downwardly bent end or toe of thehold down member 48'first comes in contact with' the innersole near thetoe portion and as'the downward movement of the hold down is continued,the hold down member 48 is straightened forcing the toe 50 and theinnersole slightly toward the point the carrier 1,1ao,as2 8 of the toetill the rigid hold down 44 is brought in contact with the lower portionof the innersole. By depressing the pedal lever still further a firmunyielding pressure may be brought to bear upon the hold down forholding the innersole securely to the last din-in the upward wi e of thelasting plates w hich tend to lift t e last; This 'operation iscifectively prevented.

the lasting operation issufliciently prooperation of drawing upandwiping in the toe portion of the upper is performed with the aid ofthe toe lasting wiper plates 102, as shown in Fig. 2. During the toelasting operation while the upper is being drawn up alongthe edge of thelast it is apt to catch upon the edge of the innersole and raise it fromthe last. By providing the yielding hold down member or toe havingengagement with the innersole near the point of the toe where it'is mostlikely to lie-caught by the upper and a firm, unyielding pressure at theball of the shoe, displacement of the-innersole during the toe lastingWhen gresscd so that the parts are no longer likely to be displaced, theoperator, in order that he may work more conveniently upon the shoe, maY release the hold down by pressing the lance lever 100'tl1us releasingthe pedal lever, as described, and allowing the 1'etractile sprin 76 toraise the post 8 and consequently t 1e hold down head and hold down. Assoon as the hold down arm is clear of the shoe, the'spring 30 operatesto rotate the block 20on the post 8 until the stop pin '26engages thestop 'pin 24 where the hold down remains in inoperative position untilrequired for use upon the next shoe to be lasted.
